The separate parts h of the plate h are also provided at their ends and on the inner side of their outer edges with inwardly directed flanges or rims hf which are l.- shaped in cross section, and which overlap the corresponding parts of the base flanges f on the tire blocks f.

The parts 72, of the plate h are also provided centrally of their inner sides with longitudinal ribs if in which are formed apertures 72, which pass through said plates and through which the bolts 9 pass, and said bolts serve to bind the parts 6 of the plate and the plate It, together, and to secure said parts to the rim and to secure the tire blocks f in position.

The tire blocks f are made of rubber, rubber and canvas, or any suitable or similar material, and the foregoing completes the construction, or the description thereof, when a single tire or a singleseries of tire blocks are employed, but in the construction shown in Figs. 6 to 8 inclusive, I have shown my improvement as applied when two tire members or two series of tire blocks are employed, to form a double tire, and this construction is the same in all respects as that shown in Figs. 1 to 5 inclusive, except that two rows of the tire blocks are employed, and the outer supplemental rim plate 6 is composed of a central member e an inner member a an outer member e and an intermediate member 6 placed between the outer member 6 and the central member 6 The members e 6 e and 6 are made up of separate parts corresponding with the tire blocks 7 the same as the parts e and k in the construction shown in Figs. 1 to 5.

With this construction the inner member e corresponds in all respects with the part c in Figs. 1 to 5 inclusive, with the exception that its transverse width is less, and the A outer member 6 is exactly the same as the vouter plate h in Figs. 1 t0 '5, and the lntermediate member e simply serves as a spacer between the parts 6 and 6 The central member 0 or the separate parts thereof, are provided ontheir underside with studs e and screws are passed 7 inwardly through said members and through said lugs in order to secure the central member, or the parts thereof, to the rim a, and said central member, or the parts thereof, are also provided with T-shaped circumferential locking ribs 6 the side flanges a of which overlap the base flanges f at the inner side of the tire blocks f, and the members e are'also provided'at their ends with inwardly directed flanges e which overlap the base flanges of the blocks f at the ends thereof. 7

The parts e e 6 and 6 are also provided with raised transverse rib members 0 through which are passed bolts 2' similar to the bolts 9 and intended to bind the parts 0 e 6 and 6 together and to lock the same to the rim plate 0 and to secure the tire blocks f in position.

The rim plate 0 is employed in this construction the same as in that shown in Figs. 1 to 5, and the details of the construction of said rim plate and of the part c which corresponds with the part It in Figs. 1 to 5 are the same, in construction and operation, as in Figs. 1 to 5, and the outer edge portion ofthe part c is the same in all respects, as the parts 6 e and c in Figs. 1 to 5 inclusive.

With the construction shown in Figs. 1 to 5, the separate tire blocks may be taken off and replaced whenever desired by simply detaching the outer plate members it, and with the construction shown in Figs. 6 to 8 inclusive, the outer tire blocks f may be taken off and replaced in the same manner by detaching the outer plate member 6 and the inner tire blocks 7 may be taken off and replaced by detaching the inner plate member 6 It will also be seen that in the construction shown in Figs. 1 to 5 inclusive, the supplemental outer side plate It forms a part of the supplemental rim member 6 and the parts of the plate it correspond with the parts of the supplemental rim member 2, while the plate cl forms a part of rim plate 0; and in the construction shown in Figs: to 8 inclusive, the outer side rim plate 6 forms a part of the supplemental rim member e which is made up of three annular members, all of which are divided into transverse parts which correspond with the tire blocks f as is also the plate 6", and in this form of construction the rim plate 0 and the plate (Z are the same as in Figs. 1 to 5 inclusive. 7

While I have shown and described the form or forms of construction which I prefer, my invention is not limited to the details of said form or forms, as herein shown and described, and changes therein and modifications thereof maybe made, within the scope of the claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with a wheel felly of a rim mounted thereon and provided at its opposite sides with locking flanges which overlap said felly, a supplemental rim mounted on said rim and comprising a plurality of sections having means engaging said locking flanges each of said sections being composed of separate parts provided with transversely and circumferentially extending locking flanges, a tire block mount- 'ed in each of said sections and having base overlap said felly, a supplemental rim mounted on said rim and consisting of a plurality of sections composed of a plurality of separate parts having lugs which engage the notches of the rim flanges, the separate parts of each of said sections having transversely and circumferentially extending locking flanges, a tire block mounted in each of said sections and having base flanges engaged by said locking flanges for securing said blocks in the sections, and means for locking the separate parts of each section together and for securing the sections to the rim, each section being secured to the rim independent of adjacent sections.

8. The combination with a wheel felly, of a rim mounted thereon and provided at its opposite sides with notched flanges which overlap said felly and provided on its periphery with a series of spaced lugs, a supplemental rim mounted on said rim and c0n sisting of a plurality of sections having means engaging the notches of the rim flanges, each of said sections being divided longitudinally to form two separate parts having transversely and circumferentially extending locking flanges, a tire block mounted in each of said sections and hav- Oopies of this patent may be obtained for ing base flanges engaged by the flanges of the separate parts for securing the blocks in the sections, and means engaging the rim together and for securing the sections tothe rim.

4. The combination with'a wheel felly, o a rim mounted thereon and provided at its opposite sides with notched flanges which lugs for securing the units of each section v overlap said telly, and provided on its periphery with a series of spaced lugs, a supplemental rim mounted on said rim and consisting of a plurality of sections having means engaging the notches of the rim flanges, each of said sections being divided longitudinally to form two separate parts having transversely and circumferentially extending locking flanges, a tire block -.3'

mounted in each of said sections and having base flanges engaged by the flanges of the separate parts for securing the blocksin the 1st day of March, 1915.
